Karl; Europa electronics come with bass and treble boost/cut switches. Each three way switch provides 6db boost, flat, and 6db cut. Peter wants to add a mid switch as well as the bass and treble switches, plus he wants a set of switches for the neck pickup and one set for the bridge pickup. So I've suggested that in addition to bass, mid and treble, he also add a low-mid and a high-mid switch; and that instead of three positions, he get five way switches with 9db boost, 6db boost, flat, 6db cut, and 9db cut.
I'm not seriously suggesting such a mod, just having fun riffing on his idea.
